Before the 1997 election, Dudley was divided into East and West constituencies, rather than North and South. Dudley South covers most of the area previously covered by Dudley West, which included Sedgley but excluded Netherton.

Dudley West was the scene of a by-election in 1994, held after the death of the ConservativeJohn Blackburn who had represented the constituency since 1979. The by-election was won by Labour's Ian Pearson, who stood for Dudley South in 1997 and held the seat, winning by a comfortable margin each time, until he stood down in 2010.

The Conservative candidate, Chris Kelly, gained the seat in the subsequent general election. However, he decided to stand down in 2015.
